Hi Carol,

Unfortunately no. It is a long and expensive process to convert the whole production flow to the new device, and there are factories still finishing lots of pre-PCN devices. This is not only due to existing wafer inventory, but also scheduling commitments in the manufacturing and testing assembly line. We should be fully moved over in 2-3 months, but in the meantime the only way to tell which version of the device you have is to check the lot trace code.

Best regards,

Sean
